Method for power conservation in virtualized environments

摘要

A system and method for enabling power conservation when making placement and relocation decisions. More specifically, a virtualized environment power conservation module enables power conservation when making placement and relocation decisions within a virtual environment. The virtualized environment power conservation module assigns virtual machines among a group of physical hosts in order to minimize the net power consumption. The virtualized environment power conservation module makes use of server power profile or real time power consumption data to make power consumption aware Virtual Machine assignment decisions. In certain embodiments, a server system exposes real power consumption (e.g. System Watts, Cumulative kWh. etc.) via system management interfaces. Additionally, in certain embodiments, the server systems may expose real power consumption via standard power profiles. These systems leverage PMBus-enabled power supplies to read the power metric information.
